FpcROUTE

FpcROUTE was developed to be console file translator application with integrated support in FreePCB. As such, it can be launched form within FreePCB or directly from a command shell.
FpcROUTE will translate a FreePCB board into an Specctra design file suitable for import into Alfons Wirtzs web based Freerouter. Prerouted wiring, FromTos, keepouts and power planes can be defined within FreePCB to control how the board is autorouted.
FpcROUTE will also perform the reverse translation by converting a Specctra session file, output by Freerouter, into a routed FreePCB board file.
The command line syntax was designed for simple yet flexible operation. The full syntax consists of the program name followed by optional switches and one or two file names:

C:> fpcroute [switches] [path1]name1[.ext1] [[path2]name2[.ext2]]
If only one file name is entered, it will be used for both the FreePCB and Specctra files. If the file name includes an extension, the name will be used as entered for the FreePCB source file; the Specctra name will use the base name with the extension changed to “.dsn” or “.ses” as appropriate. If the file name does not include a extension, “.fpc”, “.dsn” or “.ses” will be added as needed.
